Unit sends new data to the base station.
S215 dispatches the transmission of the corresponding carrier units of the N number of uplink authorization information.Specifically, can priority scheduling this is N number of
The data of the corresponding carrier units of (N-1) a uplink authorization information in uplink authorization information are sent, and are based on priority scheduling
The data send the uplink authorization finally dispatched in N number of uplink authorization information in addition to (N-1) a uplink authorization information
The MAC control information of the corresponding carrier units of information is sent.
Execute S215 in scheduling after, further, in S220, in the second Transmission Time Interval by with this
(N-1) the corresponding carrier units of a uplink authorization information send new data to the base station, and in second transmission time
In interval by with this except should the corresponding carrier units of uplink authorization information in addition to (N-1) a uplink authorization information to the base station
It sends media access control MAC and controls information, wherein N, i are respectively positive integer, N >=2, i≤N, second Transmission Time Interval
It is later than first Transmission Time Interval.
Specifically, if UE is in a Transmission Time Interval (Transmission Time Interval, TTI), such as son
N number of uplink authorization information for being used for transmission new data is received inside frame, N number of uplink authorization information and N number of carrier units one
One is corresponding, and UE can be when dispatching the transmission of the corresponding carrier units of the N number of uplink authorization information, and the N number of uplink of priority scheduling is awarded
The data for weighing the corresponding carrier units of (N-1) a uplink authorization information in information are sent, and finally dispatch N number of uplink authorization information
In except should the MAC control information of corresponding carrier units of uplink authorization information in addition to (N-1) a uplink authorization information send, example
Such as, upstream data to be sent is surrounded by 1~6, and UE receives three authorization messages, wherein an authorization message corresponds to main load
Wave unit, other two authorization message respectively correspond secondary carrier unit, and it is auxiliary at one that MAC layer can dispatch first data packet 1 and 2
On carrier units, secondly MAC layer dispatches data packet 3 and 4 on another secondary carrier unit, last MAC layer scheduling MAC control letter
Breath is on main carrier unit, and UE ultimately generates the physical layer that MAC PDU is sent to UE according to dispatch situation, after physical layer process
It is sent to base station.
Optionally, the first Transmission Time Interval in the embodiment of the present invention and the second Transmission Time Interval can refer to one
Subframe, an OFDM symbol etc. can also be the transmission time unit in the following wireless communication systems.The present invention does not constitute this
It limits.
In order to send data in Uplink Shared Channel, UE needs to receive a legal uplink authorization (in addition to non-adaptive
HARQ retransmit because it can send re-transmission in the resource of initial transmission, and adaptive retransmission needs physical down control
Resource etc. of the channel instruction for re-transmission), this uplink authorization may be obtained dynamically from Physical Downlink Control Channel, Huo Zhe
Either semi-persistent scheduling (Semi-Persistent Scheduling, SPS) is inner in accidental access response message is pre-configured with
Alright.When requesting transmission, MAC layer receives corresponding HARQ information from physical layer.In other words, which can be use
New data is either used for transmission in adaptive retransmission.It should be understood that the embodiment of the present invention in multiple uplink authorization informations, be for
Transmit the information such as new data distribution interface-free resources, sending instant.That is, UE should be advanced after receiving multiple uplink authorizations
Row screening, determines that is received in the subframe is used for transmission the uplink authorization of new data.Specifically how to determine there are rule inside agreement
It is fixed, not described here any more.
It will be appreciated by those skilled in the art that MAC, there are multiple control information, MAC control information can be buffer state report
It accuses (Buffer Status Report, BSR) and controls information, be also possible to power headroom reporting (PHR) (Power Headroom
Report, PHR) control information etc., the control of MAC involved in embodiment of the present invention information can be part, be also possible to
All.
The carrier units finally dispatched can avoid after needing to complete all scheduling for sending MAC control information
State is estimated, to significantly reduce the complexity that user equipment carries out uplink transmission.
For example, the UE for being configured with CA can be with 1 main plot (Primary Cell, Pcell) and multiple secondary cells
(Secondary Cell, Scell) is connected, and UE initiates random access on Pcell and establishes connection, the corresponding carrier wave of Pcell
For main carrier units, carrier units supplemented by the corresponding carrier wave of Scell.Wherein, Pcell be used for provide UE safety input parameter,
Non-Access Stratum mobility information of UE etc..It will be appreciated by those skilled in the art that UE only has a wireless heterogeneous networks at CA
(Radio Resource Control, RRC) connection, the change of RRC only passes through RRC reconfiguration message and completes, for Scell's
Radio Link Failure will not trigger RRC reconstruction, and only when Radio Link Failure occurs for Pcell, just triggering RRC is rebuild.In order to improve
Control information is sent to base station by main carrier unit as much as possible by the state synchronized of UE and the base station eNB.It should be understood that this
Control information in inventive embodiments can be MAC control information, be also possible to Physical layer control information, for example, physical uplink
Control channel information etc., the present invention answers without being limited thereto.
Therefore, the method for transmission information provided in an embodiment of the present invention sends MAC control in the carrier units finally dispatched
Information can avoid the state after needing to complete all scheduling and estimate, to significantly reduce user equipment progress
The complexity that uplink is sent.And the carrier units finally dispatched are main carrier units, while can be improved user equipment and base
State synchronized between standing.
Optionally, in embodiments of the present invention, user equipment can also by main carrier unit to base station send signaling without
Line carries (signalling radio bearers, SRB) data, to further increase the state between user equipment and base station
Synchronism.Specifically, SRB is used to transmit wireless heterogeneous networks (Radio as a kind of special radio bearer
Resource Control, RRC) and Non-Access Stratum (Non Access Stratum, NAS) message.For example, SRB0 is believing
It enables and does not need to establish in establishment process, SRB1 can be connected in foundation and RRC reconfiguration message in RRC with SRB2 and be configured.It will
SRB data are placed on main carrier unit and send, so that being able to maintain shape when connection of the user equipment between foundation and base station
State is synchronous.User equipment can also individually send SRB data on main carrier unit, and the application is to being single on main carrier unit
SRB data are solely sent still to be not construed as limiting what SRB data and MAC control information were sent together.
It should be understood that UE can be used for transmission according to multiple after determining to be used for transmission the uplink authorization of new data
The uplink authorization information of new data determines uplink authorization information corresponding with main carrier unit, specifically, can be multiple
Mark comprising corresponding carrier units in each uplink authorization information in uplink authorization information, for example, ServCellIndex,
In general, ServCellIndex be 0 it is corresponding be main carrier unit, it is secondary carrier unit that 1-7 is corresponding, and secondary carrier unit
ServCellIndex be to be configured by base station.As long as the mark of getting up can be corresponded for uplink authorization information and carrier units
Knowledge all can serve as the embodiment of the present invention, and the present invention is to this not enough at restriction.
Specifically, UE multiple secondary carrier units of priority scheduling before the MAC control information of scheduling main carrier unit is sent
Data send.Under normal conditions, the transmission that MAC controls information needs just be calculated after all scheduling completion.It lifts
Example for, if UE receives 5 uplink authorization informations for being used for transmission new data in a subframe, wherein including with main carrier
Corresponding uplink authorization information and 4 uplink authorization informations corresponding with secondary carrier.If the number of UE priority scheduling main carrier unit
Buffer Status Report (Buffer Status Report, BSR) control letter is sent according to transmission, and using the main carrier unit
Breath, then the buffer data of the UE after the data for having dispatched 5 carrier units are sent must be estimated first when calculating the BSR
Amount, so that more complicated when calculating BSR.
The embodiment of the present invention controls information hair by the MAC that the data based on priority scheduling finally dispatch main carrier unit
It send, can avoid the state after needing to complete all scheduling when sending MAC control information and estimate, to effectively drop
Low user equipment carries out the complexity of uplink transmission.
Optionally, in embodiments of the present invention, it includes: Buffer Status Report BSR or power headroom which, which controls information,
Report at least one in PHR.
It will be appreciated by those skilled in the art that UE is requested by uplink scheduling request (Scheduling Request, SR) to eNB
It when ascending resource, only specifies whether it has upstream data to need to send, oneself needs to send how many upper line numbers without indicating
According to.UE needs to tell eNB by BSR, how many data needs to send in uplink buffer, so that eNB is determined to the UE points
With how many ascending resource.When following event occurs, it will triggering BSR is reported: 1, the upstream data buffer of UE for sky and has
New data reaches, such as: UE sends upstream data for the first time.The BSR is referred to as " Regular BSR "；The data of high priority
It reaches, if UE has had sent a BSR, and is waiting uplink authorization, there is the data needs of higher priority at this time
Transmission, then UE can trigger BSR and report.The BSR is referred to as " Regular BSR "；UE periodically updates oneself to eNB
Buffer state, eNB are that UE is configured with a timer, if the timer is overtime, UE can trigger BSR and report.The BSR is referred to as
"Periodic BSR"；It 4, is the robustness for improving BSR, LTE provides the mechanism of a re-transmission BSR: this is in order to avoid UE
Have sent the case where BSR but never receives uplink authorization.ENB be UE be configured with a timer, when the timer time-out and
When having data that can send in any one logic channel of UE, it will triggering BSR.The BSR is referred to as " Regular BSR ".
As long as any of the above-described trigger event occurs, UE passes through the last one carrier units and sends the BSR to eNB.And when any one
Carrier units do not meet there are also surplus resources and the trigger condition of above-mentioned Buffer Status Report BSR after having dispatched data
When, UE then can send Padding (filling) BSR to eNB by the surplus resources of any one carrier units.
Similarly, when following event occurs, it will triggering PHR is reported: 1.periodicPHR-Timer time-out is with regard to upper
Report.2.prohibitPHR-Timer is overtime and path loss is more than thresholding dl-PathlossChange, just reports.3. on each
Row bandwidth, if after distributing logical channel data, it is also vacant, then it can carry out power and report.
It should be understood that being to be retouched for BSR and/or PHR and common some trigger conditions in the embodiment of the present invention
It states, the application is not limited to this.
BSR or PHR is sent using the carrier units of the last one scheduling, can be avoided needs when sending BSR and/or PHR
Current UE buffer data size or uplink transmission power surplus after completing to all scheduling are estimated, to effectively drop
Low user equipment carries out the complexity of uplink transmission.
For each uplink authorization, each logical channel buffer data can also be dispatched according to priority of logical channels, and such as
There are also surplus resources after having dispatched corresponding data for the corresponding carrier units of each uplink authorization of fruit, then can trigger
Padding BSR, and the MAC PDU that scheduling is completed is sent to physical layer process to carry out uplink transmission.
